Importing particular project in python interpreter:
----
Set the python path
export PYTHONPATH=$PYTHONPATH:/opt/stack/heat

Now python interpreter has path to heat.
All directories underlying /opt/stack/heat will be visible now.
For e.g.: /opt/stack/heat/heat/common/context.py can be imported by:

>>> import heat.common.context as ctx
>>> dir(ctx)
['ContextMiddleware', 'ContextMiddleware_filter_factory', 'LOG', 'RequestContext', '_LE', '__builtins__', '__doc__', '__file__', '__name__', '__package__', 'access', 'access_plugin', 'cfg', 'clients', 'context', 'db_api', 'exception', 'get_admin_context', 'importutils', 'logging', 'oslo_messaging', 'oslo_request_id', 'policy', 'request_context', 'six', 'token_endpoint', 'v3', 'wsgi']
>>>
